The Mark of Quality
Hannah Humpston Jewellery is registered at the London Assay Office, the renowned home of hallmarking.
Our unique Sponsors Mark sits alongside the historic symbol of the leopard’s head, the London mark of authentication.
Every piece of our jewellery over the minimum required weight will be stamped by The Goldsmiths Company Assay Office which continues to be internationally recognised as the stamp of approval and guarantee of quality and fineness.
